 The classic sandstone reservoirs in the Gulf of Suez are exploratory mature; so, explorationists should pay attention for the developed pre-Miocene carbonate sections of Eocene , U. Senonian and Turonian. This is due to the ambiguity of hydrocarbon habitat, source rocks, migration, seals and traps, which raise the exploration and development risks in the study area.

In the light of encouraging carbonate production of wells ARS-6 & WFA-1 (Eocene). 113-71, BM-61 ( U.Senonian) and Sidri-8 ( Turonian), the main objective of this paper is to construct a meaningful model for the scattered producing carbonate wells in the central province oil fields. Based on the implementation of all geological, petrophysical and engineering concepts.

To achieve this objective a detailed E-log correlation for many wells, core analysis, petrography , petrophysics and reservoir data are extensively studied.

The GR/Sonic. Caliper logs are highly helpful tools to trace the fractured carbonate intervals. Also the carbonate production of these scattered wells comes from fractured reservoirs of faulted block model specially in the areas of intersection between clysmic faults and other fault trends.

The study supports drilling horizontal wells underbalance in this fractured carbonate rocks. The downthrown blocks are optimistic carbonate targets.
